Title: Photographic cameras
IPC: G03B3/00
Filed: 1955-02-17
Abstract: 775,606. Lens mounts, photographic cameras. KAMERABAU ANSTALT. Feb. 17. 1955 [Feb. 17, 1954], No. 4817/55. Classes 97(1) and 98(2). In a photographic camera the objective is supported by a number of resilient arms so that, on focusing, the optical axis is displaced parallel to itself. Preferably, the resilient arms are spring plates 1, 2. To minimize the displacement of the optical axis O, the range of displacement of the objective 5 may be symmetrical about a central position in which the plates 1, 2 are vertical. Alternatively, the plates 1, 2 may be vertical when the camera is focused for parallel light and, the displacement of the optical axis, on focusing for near objects, used to partially compensate for parallase in a view finder. The plates 1, 2 may be apertured as at 7 and 8 for the viewfinder on a range finder. They are also apertured when they extend for the full width of the camera and the objective 5 is carried between them. In a stereoscopic camera the plates 1, 2 may be arranged between the objectives. The plates 1, 2 are sprung so that they press the objective carrier 3 into contact with a focusing screw or cam in all focusing positions.

Title: Improvements in and apparatus for determining elements present in traces in organic substances
IPC: G01N31/12
Filed: 1954-02-25
Abstract: <PICT:0762597/III/1> Elements present in traces in organic substances are determined by atomizing the organic substances in liquid form with oxygen, supplying the resulting mixture to an auxiliary flame and analysing the combustion products for the elements.  The auxiliary flame may be a hydrogen-oxygen, methane-oxygen, or illuminating gasoxygen flame.  As shown, a quartz burner is formed with four inlets, combustible gas and oxygen for the auxiliary flame entering at 6 and 8 respectively, the organic compound, in liquid state or as a solution, through a capillary tube 3, and the oxygen for atomization at 1.  The combustion chamber 10, and the spiral 12 connected thereto, are cooled by jacket 11.  The combustion products pass as fine bubbles through frit 16 into an absorbent solution in receiver 13.  A vacuum may be applied at 20.  Examples describe (1) the determination of chlorine in an alkylbenzene by burning a mixture with benzene, absorbing the products in a caustic soda containing perhydrol, and titrating with silver nitrate solution.  (2) the determination of the sulphur content of phenol by burning a solution in methanol, absorbing in distilled water containing perhydrol, evaporating the absorbent to dryness and determining the sulphur as sodium sulphate.  (3) the determination of organically-combined chlorine in waste aqueous liquids by extraction with benzene, burning the extract, absorbing, and titrating with silver nitrate solution. In the determination of metals, the metal oxides are deposited near the flame and are removed and estimated.

Title: Lifting jacks or extensible tripods
IPC: B66F3/24
Filed: 1940-03-29
Abstract: 539,944. Lifting jacks. NEW, N. D. March 29, 1940, No. 5651. [Class 78 (iii)] A jack applicable for lifting aircraft comprises three or more independently or simultaneously extensible legs which can be set beneath the load in the form of a tripod. As shown, each leg 10 is in the form of a cylinder containing a ram 12 and having a connection 14 for admitting pressure fluid. At their outer ends the rams 12 are formed with tongues 22, Fig. 4, for engagement with slots 18 in a ball head 16 adapted to engage a socket 24 secured on the aircraft. When the legs 10 have been expanded to their full extent, longer legs 10a of similar construction may be engaged with alternate slots in the head 16 and expanded to give a further lift. In a modified form, Fig. 5, the legs are formed with grooves 28 for engagement with slots 18 in a flanged cup 26 fixed to the ball 16. The supply of fluid to the legs 10 is controlled by the means shown in Fig. 6. A rotatable control shaft 34 is provided with eccentrics 36 actuating spring-returned pump plungers 38, one corresponding to each leg. Fluid is drawn from an inlet 32 past an inlet valve 42 and expelled through a delivery valve 44, passage 46, and connection 48 to a leg 10. A valve 50, in the position shown, connects all the passages 46 to the connections 48, but depression of one or more of the rods 54 will open the corresponding inlet valve 42 and stop the supply of fluid to the corresponding leg of the jack. To lower the load, valves 60 are actuated to release the pressure in each of the legs. The legs may be locked hydraulically by turning the valve 50 into a position in which the legs are cut off from each other and from the pump 38. In a third position, the legs are cut off from the pump but are hydraulically interconnected, so that relative adjustment of the legs will be allowed by the flow of fluid between them. To enable the legs to be mechanically locked in their extended position, half rings 64 pivoted to lugs 62 on the cylinders, Fig. 8, are pulled down by springs 66 into locking engagement with the rams 12. The half rings are lifted, to release the lock by arms 70 on spindles supported in lugs 68 on the cylinders and actuated by thumb wheels.
